## NAME

is\_inside\_bitmap - Tells if a point is inside a bitmap. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**int is\_inside\_bitmap(BITMAP \*bmp, int x, int y, int clip);**

## DESCRIPTION

Returns non-zero if point (x, y) lies inside the bitmap. If \`clip' is non-zero, the function compares the coordinates with the clipping rectangle, that is it returns non-zero if the point lies inside the clipping rectangle or if clipping is disabled for the bitmap. If \`clip' is zero, the function compares the coordinates with the actual dimensions of the bitmap.
